This week we’ll start with some general updates:

First, we’re excited to have some new titles coming to our e-store — the first since our blog relaunch earlier in the year. I’m doing the last touches on two e-books now and will be adding Yajilin Battleships by Serkan Yürekli and Plenty O’ Pentominous 3 by Grant Fikes and Murat Can Tonta to our web store over the next two weekends. Watch for additional posts here when these fun collections are available for purchase.

Second, we have not found any quick fixes to the issues with logging into the solving/fave applet. This seems to be due to updated browser security checks when connecting to external sites. The fix likely requires moving the applet and database to be hosted on our servers and we are working with the external developer to see if this is possible, or if we should find an alternative self-hosted tool.

Our most recent week of Cross the Streams puzzles can be found in this PDF and the solutions are all grouped in this PDF and have also been linked to the individual posts.

We have a solving video for two of this past week’s puzzles. First is a solving video for my Cross the Streams (LITS):

We also have a video for the Saturday Cross the Streams (audiobook) from Grant Fikes:

This upcoming week will feature Cave puzzles including one variation.
